Data Event Response to the June 26, 2019 M6.2 Earthquake 5km SE of Aserrio de Gariche, Panama

Written by David Phillips and Beth Bartel Posted: 27 June 2019

Event Summary

A magnitude 6.2 earthquake occurred at 05:23:50 UTC on August 21, 2018 (12:23:50 local), 5km SE of Aserrio de Gariche, Panama. For more information, see the USGS Earthquake Hazards Program event page.

UNAVCO Response

GPS Real-time Data Streams
Signals from this event were recorded by one GPS/GNSS station operated by UNAVCO within 1,700 km of the epicenter that was streaming high rate (1-sps / 1 Hz) data in real time (Figures 2 and 3). These data allowed peak ground displacements (PGD) to be calculated automatically from the displacement trace (Figure 3). Dynamic ground displacements of up to ~22 mm were recorded by real-time site CN20 as the surface wave generated by the earthquake propagated away from the epicenter. No displacements were recorded by more distant real time streaming stations. Note: figures and findings are preliminary and subject to revision.

GPS/GNSS Data - Custom Downloads for Post Processing
UNAVCO has downloaded high-rate 1-sps (1 Hz) data from two GPS/GNSS stations (CN20, TGPM) within 200 km of the epicenter for a 3-day time window around the event (± 1.5 days). Higher rate 5-sps (5 Hz) data have also been downloaded from these stations for a 6-hour time window around the event (± 3 hours). A map of downloaded stations is shown in Figure 4. These data are available as RINEX files for post processing from the UNAVCO high rate data ftp site.

GPS/GNSS Displacements
Coseismic offsets from this event will be estimated by the GAGE GNSS Analysis Center Coordinator (ACC), Professor Tom Herring (MIT). When available, offset estimates will be reported in an event file at the event products ftp site and in the GAGE GNSS analysis time series offset file.
